IIVIIPIRO'VED RAILWAY-CIAB COUPLIN'G.

The chednle referred to in these Lettera Patent and making part of the same To all 'whom it 'may concern:

Be it known that- I, WILLIAM J. EVANS, of Homer,

' inV the county of Hamiltoii,'and State of "v1o\va, have invented a new and useful Improvement in Car-Coup lings; and I do hereby declare that the following is a lull, clear, and exact description thereof, which will enable those skilled'in the art to make and use the same, reference heilig had `to the accompanying drawings forming part of this specification.

This invention relates to a new and useful improvement in car-couplings, whereby a simple andefficient device maybe obtained by which the ears may be coupled self-actingly when -the said device has been properly set. This invention consists in the arrangement with coupling-pin having a vertical guide of' a hinged setting lever for holding` the pin above the opening for the link, and for being tripped by the link to let the pin fall when the link has passed in also in the arrangement with the same ot' a balancing 'tongue to hold the links in a horizontal posit-ion so as to enter the mouthot' the -d1'a\ v-head of an approaching car.

The drawing represents a longitudinal section of a part ot' coupling devices, constructed according to my improvements.'

A represents a guide for the coupling-pin B working through a. vertical hole in `the draw-head'C, and

. provided with a pin, D, or other stop to prevent being drawn out. This guide maintains the `coupliugwpin always in line with its hole.

E represents a.v hinged tripping-arm, connected to the top ofthe guide, or to the crossbar F, connecting the guide and the piu', and also projecting 'downward in a hole in the drawfhead. This hole is elongated, and

near the fiont wall thereof, in the longitudinal recess of the draw-head, is a notch, G., into which thefoot of -thesnid tripping-arm is placed when it is desired t-o hohl the pin up tocouple the cars.

The link H being forcedinto the bell mouth of the draw-head, will strike the tripping-arm and push it out of the. `notch G, when the pin B will fall and engage the link.

I represents a weighted tongue arranged in therecess ofthe draw-head so as to receive the end'ot' the link under its front end, and thereby maintain the link in a horizontal position, so as to enter the/month ot' a draw-head on an approaching cai', and thereby effect the coupling self-actingly by knocking the tilting arm out ot' its notch. Y

The mouths of the buffer or draw-heads, and the recesses behind-them, should be'soarranged as to peri, mit suicient lateral play for the links, without permitting them to be so far movedas to obstruct the falling ofthe pins through them.

Having thus described my invention,

' That I claim as new, and desireto secure by Letters Patent, isv l. The combination with the draw-heads and the pins B of the guides A and tripping-arms E, when arranged substantially fasspecified.

2.' The combination with the draw-heads, pinsT guides, and tripping-arms, ofthe weighted tonguesfL,

when larranged substantiallyas specilied.
